Today is bison marrow bones. I try to give them meat at least once a week and today we went to feed store for food and they freaked out when they saw them in the bag, even without opening them at all. It looked liked bagged evidence from CSI or something. SO gross. But they are so happy, sprawled out on the ground, methodically eating it. I wish I had the space to feed them raw, but alas, I have a tiny fridge/ freeze in my apartment.
